Misc STATES FF! Q E,

To all whom it my comem.

Be it known that I, JOHN A. Hum-ma,

a citizen of the United States, residing at Indianapolis, inthe county of Marion'and State of Indiana, have invented certain new and useful Improvements in Starter Gear Bands, of which the following is a specification. I v vThis invention relates to gearbands designed primarily. for use in connection with a pinion of an engine starter and is applied to the periphery of the fly wheel of the engine, and the prime feature of the invention is in so constructing the ends of the gear teeththat said gear maybe rendered universal, or 'may be so constructed as to .be rendered interchangeable, and when ren dered universal the same gear may be used in connection with v'pinions that move into engagement therewith from opposite faces of the fly wheel; and'when constructed to render the-same interchangeable, the band may be reversed on the fly wheel when one end of the teeth becomes so worn as to render them practically useless.

A further feature of the invention is in so constructing'the angle or curved faces at the ends ofthe teeth that they will exactly correspond with the curvature or angle of the ends of the teeth on the starter pinion, thereby maintainin a broad contact face between the teeth of t e gear band and pinion,- and consequently reducing the wear-to a minimum and insuringa more positive engagewent between the gear and pinion when the pinion is 'moved into mesh with the gear.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanyin specification. ea In the accompanying rawings,

Figure 1 is an elevationof a portion of a gear band showing a starter pinion in en agement therewith, 1.

igure 2 is a frahgmentary. perspective c5 view of the gear ban g Figure 3 is a plan view of that form of gear shown in Figures 1 and2, and

Figure 4 is a similar view showing the manner ofconstructing an interchangeable to gear.

' In applying gear bands of this nature to use, it is customary to secure a band, referably ofsteel, to the periphery o the usual formof fly wheel connected'with a 'motor and when the gear is of theuniversal starter type the band is preferably fixed to the fly wheel, and when the gear is of an interchangeable type it may be removably secured to the fly wheel in any suitable mann'er.-' so In rendering the band 1- universal, the ends of'the teeth 2 are ta ered alike at both ends, the tapered faces 3 ing substantially at the same angle or curvature as the angle 0r curvature of the teeth 4 of the starter.- p1n1on 5, and as both ends of the teeth in this instance are similarly tapered, the

same band may be employed with pinirms' which move from either direction when ing moved into band; I r

Heretofore it has been thecustom to pro-V vide a band. for each .difierent construction ofpinion and consequently the teeth of the engagement with the gear 7e gear were beveled or rounded at one endt'B percent less stock, as the universal gears will receive the pinions of the starter mov- 8 ing from either side of the fly wheel, the mounting of the starter pinion at opposite sides of the fly wheel being rendered necessary on difierent makes of automobiles. In rendering the gear band interchangeable,

that is, in instances where the band is, to be used in connection with a pinion moving from one'direction only, the 'ends of the teeth 6 are tapered in opposition to each other so that when the ends of the teeth at one side-of the band become worn, or otherwise damaged, the band 7 may be removed from the fly wheel and the opposite edge thereof brought into play with the pinion co-operati .or practica 1y doubling the life of the gear band or making two bands in one.

therewith, thereby increasing In applying this form of band to use it may be set into a. groove at the corner edges of thekfly wheel or may be secured around the peripheral face of the fly wheel and when a universal band is' em loyed the I inion may move towar the gear from eit er face of the fly wheel.-
